In order to maximize the length of twists on my natural 4a/4b hair, does it matter if it's done on wet or dry hair? Also as far as what to twist the hair with, If I deep condition with something before twisting (such as aussie moist), should I put a leave in then gel (clear ecostyler) or can I put the gel on directly after I rinse the dc out, that is if I'm twisting on wet hair?
